Answer:
cos Ф= -15, sec Ф= -1/15
sin Ф= -8, csc Ф= -1/8
tan Ф= 8/15, cot Ф= 15/8
Step-by-step explanation:
cos Ф=x,
sin Ф=y
tan Ф=y/x
sec Ф=1/x
csc Ф=1/y
cot Ф=x/y
Answer: The number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .
Step-by-step explanation:
Given word = "EQUATION"
Total letters = 8
Total Vowels (EUAIO)=5
Total number of ways to arrage letters = 8!
Number of ways to arrange vowels in alphabetical order = 5!
Then, The number of ways that all the vowels are in alphabetical order will be :

Hence, the number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .
Answer:

Answer:
1. x = -1 or x = -3
2. x = 1 or x = -3
3. x = 3 or x = -7
4. x = 1/2 or x = -2
5. x = -2/3 or x = 4
Step-by-step explanation:
I'm guessing these are what you needed, you didn't specify.
